Sph Simulation Of Plastic Deformation In High Velocity Impact Welding Process Of 6061-T6 Alloy Plates

In this study, the plastic deformation process of two plates of aluminum alloy 6061-T6 was simulated at different collision point velocities using the method of smoothed-particle hydrodynamics (SPH). The results of numerical simulation were compared with the results obtained in experimental and theoretical studies of other authors. The data obtained indicate that the SPH method reproduces the wav. interface between the plates, which was previously observed in numerous experiments. In addition, SPH simulation allows one to study in better detail the features of plastic deformation occurring near the interlayer boundaries, in particular at the vortex zones.
